Of the accompanying drawings:

Figure 1 is a bottom perspective of footwear embodying the invention.

Figure 2 is a top plan of the sole used therein. Figure 3 is a section on line 3-3 of Figure 2. Figure 4 is a section on line H of Figure 2. Referring to the drawings, the numeral I0 designates a shoe upper to which is secured, as by stitching ll about the margins of the sole and nails I2, I 2 in the heel portion, a rubber sole IS.

The sole l3 may be formed-on its upper margins as at H to simulate welting and at the inside of the shank of the sole on the top thereof there is provided an integral raised portion l4 to support the arch of the foot. On the bottom of the sole at the shank under the raised portion l4 there is preferably formed a recess [5 whereby 3.0 the edge of the sole at the inside of the shank will be substantially of uniform thickness with the rest of the sole edge. The stitching l l extends into the recess l5 and serves to draw the archsupport l4 well up into the bottom of the shoe.
